Self-assembly battery for rear rack 48V 13s7p 20,3Ah with charger and bms
Product for advanced users.
The product for advanced users does not have marked areas for BMS mounting. The order of connection should be established by yourself. The set includes: battery case and package.
We do not provide assembly instructions for kits for advanced users. However, you can use one of the video instructions available for begginer kits. We provide also technical support through our service department.

WHICH KIT IS THIS BATTERY FIT FOR?
Self-assembly e-bike battery The battery is ideal for installation with City and Trekking conversion kits.
Batteries should not be used with MTB conversion kits.
The maximum discharge current of the battery is 30A (our Self-assembly batteries do not support conversion kits above 1500W).


Advantages of assembling the battery yourself:



The kit includes:
BATTERY PACKAGE 13S 7P
Lithium-ion package. It is the main element for building a battery. After soldering the correct BMS, it is ready to work.
The type of cells used to build the package: Samsung INR18650-29E
Estimated range: 97km
- at a speed of 25 km / h
- no wind, on flat asphalt
- without power assist, driving "on the throttle"


BATTERY FOR TEAR RACK REAR
The housing includes a 5.5 / 2.1 charging socket.
The kit also includes a rear rack.
BMS
During charging, it balances and aligns individual sections so that they do not exceed the maximum safe voltage of 4.2V / cell. It automatically cuts off the charger if any of the cells are close to being reloaded.
During discharge, it makes sure that we do not discharge the battery too deep. In the event that any of the cells is already discharged - the BMS will cut off the power supply to the bike in order not to damage the batteries.
He tries to align the cells so that they always have the same voltage. This extends the service life and failure-free operation of the entire power supply.


CHARGER 13S 2A
Fast automatic charger for LiIon and LiPoly batteries (lithium-ion and lithium polymer). No configuration required, it works straight away. After the battery is charged, the charger switches to standby.
We recommend not to exceed 2A of the charging current (for small batteries), e.g. with a different charger.
2A is the maximum current that does not degrade this battery. We also remind you that properly used battery should be charged after each ride, which significantly extends its life. Thanks to this habit, the 2A charger will recharge it in a short time and in optimal conditions.
ADDITIONAL ACCESSORIES
Additional accessories include: keys and a set of mounting screws.

Suggested place of BMS assembly

ASSEMBLY OF THE BMS
Recommended location for BMS (pictured).
Maximum BMS thickness: 16mm
Note:
Be sure to connect the charger to the batteries in the correct order. ALWAYS connect the charger to a 230V socket first and then to the charging socket. DO NOT connect upside down. This can quickly damage both the charger and the BMS installed in your battery. Reverse connection causes the effect of sudden charging of the output capacitors of the charger through the BMS socket. This is accompanied by the flow of huge current that can damage the plug, socket, BMS mosfets or even the charger transistors.
The real capacity of a package (available capacity) is always lower than the nominal capacity of a package (rated capacity of its cells). It is assumed that a ready battery based on a package will have about 10% lower real capacity than the theoretical rated capacity. It is caused by many factors, such as the decrease in the capacity of the cells under load, or leaving the unused capacity by the BMS (discharge to the minimum cell voltage to about 2.7V) in order to extend the life of the battery.
